NiSi JetMag Pro – Prolock Luminous Adapter Ring
The NiSi Prolock Luminous Adapter Ring is an upgraded adapter designed for the JetMag Pro magnetic filter system, built specifically for photographers and videographers working in low-light conditions or seek an extended locking mechanism.
Featuring glow-in-the-dark lock markings and an enhanced ProLock locking mechanism, it allows for faster, more intuitive mounting and secure attachment of filters even in complete darkness.
Available in 58mm, 67mm, 72mm, 77mm, and 82mm thread sizes (more will be announced soon), it integrates seamlessly across a wide range of lenses.

Built for Low-Light Photography With Glow-in-the-Dark Lock Markings
Created with night and low-light photography in mind, this adapter ring is ideal for astrophotography, star trails, and landscape photography. When visibility is limited, the luminous markings provide instant orientation of the locking position, allowing you to align and secure your filters quickly without relying on bright lights that could disrupt your night vision or workflow.
Special luminous indicators absorb ambient light and remain visible in the dark, giving you immediate visual feedback on the locking position. This makes mounting and aligning your filters faster and more precise, even when working in near-total darkness.

Enhanced ProLock System Optimised for Rotating Filters
The upgraded ProLock design features a significantly enlarged locking area compared to standard adapter rings, delivering a more secure connection to your lens and reducing the risk of accidental loosening during use. This added stability ensures your setup remains reliable while shooting in demanding conditions.
The adapter ring maintains a firm hold even when adjusting the True Color CPL or the True Color 1-5 Stops VND. Rotational adjustments transfer less force to the ring itself, allowing it to stay securely locked to the lens while you fine-tune your filter settings.
Knurled Grip for Reliable Handling
A precision-milled knurled surface provides a confident grip in all conditions. Whether you are wearing gloves, dealing with cold temperatures, or working with wet hands, mounting and removing the ring remains quick and secure.

JetMag Pro Magnetic Compatibility With Full System Integration
Once attached to your lens, the JetMag Pro magnetic system allows filters to snap into place instantly. This enables fast transitions between ND, CPL, VND, and creative filters without the need for threading, improving efficiency in the field.
The adapter ring is fully compatible with the JetMag Pro ecosystem, including ND filters, CPL and VND filters, Natural Night, Star Soft, and magnetic front caps. This ensures a versatile and streamlined workflow across your entire filter setup.
Lightweight and Durable Construction Designed for Confident Shooting
Constructed from high-quality aluminium, the ring is lightweight yet robust, offering excellent resistance to corrosion and harsh environmental conditions such as coastal spray or alpine cold. It is designed for long-term durability without adding unnecessary weight to your kit.
Whether you are capturing the Milky Way in a remote dark-sky location, shooting star trails, or working through changing light at sunrise or sunset, the NiSi Prolock Luminous Adapter Ring provides a more secure, visible, and reliable connection between your lens and your filters.
